To all whom t may concern:

Be it known that I, JOSEPH LAGUIONIE, a citizen of France, and "a resident of Paris, France, have invented new and useful llmprovements` in rlypewriting Machines, of which the following is a specification.

rlhis invention relates to a device applicable to typewriting machines to facilitate the copying of writing, letters, signs or the like.

llt is the object ot the invention to provide improved means to permit the direct copying of writing or printing matter, signs, or tracings on a typewriting machine and enable a single or a number of carbon copies also to be obtained.

l attain this object by means ot an apparatus in the form of a translucent or transparent roller which is rendered luminous by interior lighting or self-luminosity and intended to replace the solid rubber roller or platen such as is generally used in typewriting machines.

The invention consists therefore in the lirst place in substituting a transparent roller (such as glass) for the opaque roller usually used in typewriting machines and in utilizing this transparent roller for the striking of characters and for direct impression on the sample placed under the sheet to be reproduced. i

ln this manner the necessity of watching the keys and the text to be reproduced while the operator is typing is avoided. rllhus loss of time and the mental etl'ort required to retain the phrase in the mind and the omission and substitution of words isavoided. iClerical errors and errors `of punctuation are also avoided.

For use when making a plurality of copies, :necessitating the interposition of a great number ot sheets of paper, with interposed carbon sheets and the thickness of the sheets becomes such that the transparency is insuliicient to enable the matter to be copied, means cooperative with the aforesaid means have been provided, which means attains the advantages above enumerated. rlhe apparatus Jfurther comprises a second transparent, semi-transparent or opaque roller moved by the initial transparent roller or by the unwinding of the sample in the vview of the operator gradually as the copying advances.

'llwo devices are thus provided, the one utilizing solely the luminous striking roller for two copies, for example made directly 1923. Serial No. 637,900.

on the sample applied to the luminous roller, the other device utilizing the luminous roller with or without lighting, according to requirements, for the striking of the charac.- ters with the sample applied to and being unwound on theiopaque or transparent roller which is associated therewith. This additional roller can be of a diameter greater than that of the platen or of a small diameter with a rocking` movement for eliecting the movement of the sample.

Reference is made to the accompanying drawings which illustrate devices in accordance with the present invention.

Figs. 1 and 2 show two constructional forms of the transparent and luminous roller.

Fig. 3 shows the coupling of the luminous roller with a secondary opaque or trans-l parent roller in the'case where the direct transparency cannot .be utilized on the platen.

Figs. 4 and 5 are modified constructional forms of the means for actuating the two rollers.

Figs. 6 and 7 are two further constructie-nal forms shown in perspective comprising the luminous platen combined with the secondary roller and the controlling and actuating means therefor.

F igst 8 and 9 are respectively end elevations o the opposite ends of Fig, 6.

Fig. 10 is a-front elevation shown partly in section.

rlFhe roller A (Fig. l) may be constructed otany suitable transparent or translucent material such as polished or unpolished glass. rlhe ends are provided with milled knobs or manipulating members l and lighting means, such as 2, shown in ,this instance as electric incandescentlamps. It for any reason the surface .of the glass platen is considered to be too hard and it is desired to damp the shocks, the glass roller could be covered with a sleeve A" (Fig. 2) et" transparent or translucent Hexible material such as colorless rubber, Celluloid or like material.

The roller-above described is actuated in a typewriting machine as. an ordinary opaque roller.

lt is rendered luminous at the desired moment by interior lamps placed behind the exterior surface, the lighting being effected by a switch of any suitable type.

Where a multiple number of copies of lll@ l12 which has a rockable movement and luminous and, means to permit of 'or memorandum of the samp the sample isjrequired as very frequently In order to occurs necessitating the interposition "of a roller B it large number of carbon sheets, thus decrea's- 12 from contact with the roller B by means ing thetransparency, a transparent' or ofthe finger lever 14.
